SPECIFICATION forming part of Letters Patent No. 456,906, dated July 28, 1891.

Application filed September 18, 1890. Serial No. 365,342. (No model.)

To all whom it 11mg concern.-

Be it known that I, JAMES K. P. PINE, of the village of Lansingburg, county of Bensselaer, and State of New York, have invented a new and useful Improvement in Machines for Infolding the Edges of Cuff and Collar Blanks, of which the following is a specification.

Myinvention relates to improvements upon To that class of machines that are used to turn in the edges of the fabric blanks of cuifs and collars before united them; and the object and purpose of my invention and improvement are to adapt this class of devices to infold and gather the rounded end and corner edges, as well as to infold the straight side and end edges of the blanks, so that the collars or cuffs when finished will have a uniform appearance.

2o Accompanying this specification, to form a part of it, there are six sheets of drawings containing eight figures illustrating my invention, with the same designation of parts by letter reference used in all of them.

Of the illustrations, Figure 1 is a top view of a mechanism containing myinvent-ion and shown as adapted to infold the straight side and end edges of cuff-blanks and to gather and infold the rounded corner edges thereof.

0 Fig. 2 is a central longitudinal section taken on the line or w of Fig. 1, and with the, end infolders shown as moved inwardly to form the end infolds in a cuff-blank. Fig. 3 is another section of the same parts shown at Fig.

2 and also taken on the line as a," of Fig. 1, with the end-infolding parts shown as moved outwardly for the insertion of a cuff fabric blank. Fig. 4 is a section taken on the line 00 x of Fig. 1, with the collar or cuff holder plate shown as down on the bed. Fig. 5 is another section of the same parts that are shown at Fig. 4, taken on the line 00 x of Fig. 1, with the cuff or collar holder plate shown as raised from off the bed for the insertion of a 5 fabric blank.- Fig. 6 is a top view of the same mechanism that is shown in the other figures, adapted to infold the edges of collar-blanks and illustrating a modified form of holderplate. Fig. 7 is a plan view of a part of a cuff 5o fabric blank which has had its side and end edges turned in by the mechanism illustrated at Figs. 1, 2, 3, 4, .and 5; and 8 is a plan view of a part of a collar fabric blank which has had its side and end edges infolded by the mechanism shown at Fig. (5.

The several parts of the mechanism-thus illustrated are designated by letter reference and the function of the parts is described as follows:

The letter T designates the table of the machine, forming at its center a bed B, on which the fabric blanks to be infolded on theiredges rest. This table rests on supports S S, as shown at Figs. 4 and 5.

The letters F and F desi nate side-edge infolders, each of which is connected to and arranged upon the inner end of a slide-plate cl, adapted to move reciprocatingly in guides g. Each of these side-edge infolders F and F on its inner edge and lower side of the lat- 7o ter is made with a rounded surface I), as shown at Figs. 4 and 5, and each of these sideedge infolders F and F is operated to move toward the other or outwardly on the bed B by means of a hand-lever L, that is pivoted to the slide-plate (l of the side-edge infolder F, and which lever I. at its lower end P is pivoted to a link Z that at the end opposite to that which is pivoted to the lever L is pivoted to the long arm of the lever L which latter has a fulcrum-pivot 19, connected to the stud I, and at its lower end is pivoted to the link Z with the latter pivoted to the lever Z for a fulcrum at 19 and at its upper end 19 is pivoted to the slide-plate cl of the side-edge infolder F within a slot S, made in said slideplate, as shown at Figs. 4 and 5, so that when the lever L, by means of its handle H, that is projected up through the slot S made in the slide-plate d of the side-edge infolder F and thereat pivoted, is moved inwardly the two side-edge infolders F and F are moved toward each other.

The letter D designates a holderplate, and its function is to descend onto fabric blanks B", placed upon the bed B, and to hold the same in place while the edges of the blank are subtending the holder-plate infolded on the edges of the latter, and this holder-plate is operated as follows:

The letter A designates a curved arm that at its inner end is attached to the top surface ICO 0f the holder-plate D, and which arm A connects with a stud d and the latter with an arm A that is at its outer end V pivoted to the upper end of the link 'i, which latter at-its lower end is pivoted to the foot-treadle T as shown at Figs. 4 and 5, so that when the foottreadle is pressed down by the operator the holder-plate D descends onto the bed 13.

The letter W designates a weight, and O a cord connecting said weight, with the outer end of the arm A and the function of this weight and connected cord is to raise the holder D from off the bed B when the footpressure of the operator is moved from the treadle T The letter Y designates a slot, madein the arm A and T a set-screw for adj ustably connecting the arms A and A thereat.

The letters E designate the end-edge i11- folders, which are adapted to be moved toward each other, and also, after being thus operated, to swing in at their sides on a pivot to gather in and infold the rounded corners or edges and tothen move outward, and to thus operate these end-edge infolders. They are preferably constructed as follows: Their inner edgesare made to correspond in concavity to the rounded edges of the holder-plate and their inner edges are each rounded olf on their under sides, as designated at m, Figs. 3 and 4. Each of these infolders E is constructed with a slide plate or tongue d adapted to move in guides (7 formed in the table T, and each of them is divided in two parts 6 e and each of which latter is vertically and loosely pivoted to one of the slideplates or tongues d by the pivot-bolt designated at 19 Figs. 1, 2, 3, and (3. The rear ends of these parts 6 6 back of where pivoted are made with bevels 19 The letter L designates levers, of which there is one for operating each of the end-infolders E. Each of these levers L is passed down through a slot S, made in one of the slide-plates or tongues d at its lower end, and at 19 is pivoted to one of the table-braces b for a fulcrum, as shown at Figs. 2 and 3. The pivot-bolts p are provided with an encircling spring o, arranged between the heads 72, and each of the parts 6 as shown at Figs. 2 and 3.

The letter R designates a bar arranged on the side of each of the levers L and the letter 8 designates a spiral spring, one end of which connects with the upper end of each of the said levers and the lower end of which connects with one of said bars at each end of the machine. This bar R extends down through the slot 8, made in the slide-plate or tongue (1 of each of the end-edge infolders, and the letter K designates a sleeve arranged to encircle each of said levers L so asto slide thereon as actuated by the bar R, and eonstructed so that said sleeve will, as the levers L are moved inwardly at their upper ends, engage with the inner end of the slot 8, made in each of the slide-plates or tongues (1 and to move the latter and the parts 6 a connectedly and inwardly.

The letter G designates a grip-lever that is arranged on each of the levers L, and each of these grip-levers has a handle end 71 projected upwardly, so that it maybe graspedin connection with the handle ends of each of the levers L These grip-levers are each of them pivoted at their angle a to the lever L and at their short arm to each of the bars R. \Vhen these grip-levers are grasped and each drawn in toward the handle of the adjacent lever L the sleeve K 011 each of the latter is forced downwardly, so as to be away from its engagement with the slide-plate or tongue 01 and as the inward movement of the upper end of each of the levers L is continued the front edge of each of the levers L above the sleeve K enters between the bevels b forcing the outer ends of each of the end-infolders e apart, and thus causing their inner ends to approach each other. Each of the end-infolder parts a e are adapted to rise on the pivot-bolts 13 against the force of the spring 1), encircling said bolts, on which they fit loosely, and they are each transversely hinged or pivoted at p, as shown at Figs. 2 and The letter W designates a wedge that is pivoted at p to each of the levers L and extended inwardly, so that as eachof the levers L is operated, as before described, to spread apart the rear ends of each of the end-infolder parts 6 said wedge underruns their outer ends so as to depress their inner ends and make the infold better defined by forcing their inner ends down on the edge of the holder-plate.

The letter P designates gas-pipes made to enter the holes 0 (shown at Figs. 2 and 3,) by which gas may be burned beneath the bed to-heat the same, and thus make more permanent the infolds in the blanks B In the apparatus shown at Fig. 6 the holderplate D is made with its endsU connected to the body part of the plate by means of a hinge h, and this so made to facilitate the removal of the infolded blank from the holder-plate.

Each of the slide-plates or tongues d d is constructed with stops (1 to regulate the distance at which they shall move. These stops are made operative by means of a slot S formed in the slide-plate or tongue, and an arm d upwardly projected through said slot from a plate P arranged 011 the under side of the slide-plate or tongue d and table T, and set-screws t arranged in projections 92 and n on the table at each end of said slots. The slide-plate or tongue (1 of the side-edge infolder F has a stop d arranged at one side of the slide, the latter being constructed to move withv the stop between two projections n and 127, which are offset from the guideplate P with each of the projections n and 92 provided withv a set-screw t t.

The letters 0 designate slots made in the supplemental plate P and t designates bolts having heads t and nuts 25 said bolts being arranged in said slots with the heads resting on the plate P and the nuts t on plates 1) below the slot, the function of these bolts thus constructed and arranged being toadjust the plate P and the lever L pivoted thereto, relatively to the bed when using differing sizes of the holder-plates D.

As thus made and arranged when a cuffblank is placed on the bed B of the mechanism shown at Figs. 1, 2, 3, 4, and 5 or a collar-blank of the bed B of the apparatus shown at Fig. 6 (after the holder D in either instance has been raised by the foot-lever) and the latter is operated to press down the holder-plate to hold in place the blank with its edges projecting beyond the edge of the holder-plate, in which condition the side lever L is operated to move in the side-edge infolders F and F so as to have their curved under edges carry the edges of the blank where lapping past the holder-plate up over the edge of the latter and thereat press down the edges of the blank on the holdenplate. Then this has been done, the end-edge infolders E are operated by their levers L to move inwardly, so that their under edges will carry the lapping part of the blank edge over the ends of the holder-plate and by continuin g the movement of these levers L and operating the grip-lever G, as before described, the parts 6 e of the end-infolders are caused to swing in toward each other, so as to gatherand infold the lapping parts of the blank at the rounded corners, and by the raising of the rear ends and depressing of the front ends of the parts c e the infolds are impressed into the blank, the heated bed B facilitating and insuring a well-defined infold. This infold is formed by the edge of the fabric blank where lapping over the edge of theholder-plate, and the pressure applied thereto by the infolders aided by the heated bed. When the infolders are moved back and from off the holderplate, the latter is raised from off the bed and the blanks are removed from the holderplate and are ready to be joined with their edges in line with the infolds turned in, and thus the edges of the articles will be uniform when sewed.

While I have shown the divided parts 6 e of the end-infolders as being adapted to be depressed at the front, yet, if desired, this part of the construction may be omitted, it. being merely an adjunct means to more thoroughly impress the infolds into the blank.

The manner of operating the end-edge infolders to gather in the infolds upon rounded edges may be varied so long as they are connectedly operated to move inwardly toward each other, and then in sequence to each on their divided connection swingin toward each other to gather up the laps in the rounded portion of the infolds. The form of the endedge infolders E may be varied, so as to make a regular curve at the ends of the collar-tab, as shown at Fig. 6, or a curve at the corners with an intermediate straightinfold, as shown at Figs. 1, 2, 3', 4, and 5. As thus made and arranged one of the end infolders may be used without the other, and without the side-edge infolders, particularly when the blanks to be infolded are of a rounded form, such as are used on collar'tabs or the capes of womens collars in which the infolds to be made are gathered in by the swinging in toward each other of the divided parts e c of the infolders.

While I have described my invention as adapted to infold the edges of cuffs or collars,

it may be used to infold the edges of other' articles where like infolds are required.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
